エレニンについてホワイトハウスが文書を発表

地球に接近する彗星エレニン。
これが中性子星で、大地震を引き起こすという噂が流れ、
続いて、そのエレニンについてホワイトハウスが文書を発表?

たぶんその文章というのはこれ↓ ?

でもこの文章、日付が2010年10月15日になってるし、
(エレニンの発見は2010年12月10日)
内容も、「天体衝突の危険。まあそんなことはないだろうけど一応調べといて」みたいな・・

EXECUTIVE OFRCE OF THE PRESiDENT
OFFICE OF SCIENCE AND TECHNOLOGY POLICY
WASHINGTON, D.C. 20502
October 15,2010

The Honorable Bart Gordon
Chairman, House Committee on Science and Technology
United States House of Representatives
2321 Raybum House Office Building
Washington, D.C. 20515
The Honorable Ralph M. Hall
Ranking Member, House Committee on Science and Technology
United States House of Representatives
2321 Raybwn House Office Building
Washington, D.C. 20515

Dear Chairman Gordon and Ranking Member Hall:
This letter relates to Section 804 of the National Aeronautics and Space Administration
(NASA) Authorization Act of 2008, which directs the Director of the Office of Science and
Technology Policy (OSTP) to “(I) develop a policy for notifying Federal agencies and relevant
emergency response institutions of an impending near-Earth object threat, if near-term public
safety is at risk; and (2) recommend a Federal agency or agencies to be responsible for –
(A) protecting the United States from a near-Earth object that is expected to collide with
Earth; and
(B) implementing a deflection campaign, in consultation with international bodies^ should
one be necessary.”
Current and Prospective Near-Karth Object (NEO) Detection Activities
As you are aware, NEOs are asteroids or comets whose orbits bring them within a set
distance of the Earth,8 with a portion of these objects traveling sufficiently close to make an
eventual collision a possibility. No NEO large enough to present a hazard is known to be on a
collision course with the Earth, and the probability of an impact by such a NEO is extremely low.
Nevertheless, incidents of this nature have occurred in Karth’s geologic past, and our immediate
neighborhood of the Solar System is continually showered by very small, non-hazardous objects.
Indeed, a steady stream of these objects enters the Earth’s atmosphere on a daily basis, consisting
mostly of dust-sized particles and estimated to total some 50 to 150 tons each day. Thus, however
remote it may be, the possibility of a future collision involving a more hazardous object should not
be ignored.
1 In genera! terms, tins distance is- equivalens to about one-third the average distance of the
Earth from the Sun.
